As a continuation to the community wish expressed last year to start a musical score transcription project [1], I'm investigating what is needed to make it happen.

The biggest hurdle seems to be how to separate content from layout. On the one hand users should be able to define which part to work on (a staff, a voice, an instrument, lyrics...), otoh they should be able to select which elements to render for different representations. For instance a single page has all parts but just for one page, a complete score has all the parts for all pages, a piano part has only the piano staffs for all pages, etc.

Lilypond can handle different layout representations, but of course the content selection has to be prepared before launching the desired layout rendering.

Any ideas about how to deal with this situation?

Cheers, Micru
